A retrospective study of ovarian tissue cryopreservation in female patients with hematological diseases for fertility preservation.

PURPOSES: To investigate the effect and safety of ovarian tissue cryopreservation (OTC) for fertility preservation in female patients with hematological diseases. METHODS: We designed a retrospective study. The clinical data of patients with hematological diseases undergoing OTC admitted to Peking University People's Hospital from April 2017 to January 2023 were analyzed and summarized. RESULTS: A total of 24 patients were included in the study, including 19 patients with malignant hematological diseases and 5 patients with non-malignant hematological diseases. The former included 14 patients with acute leukemia, 1 patient with chronic leukemia, and 4 patients with myelodysplastic syndrome, while the latter 5 patients were aplastic anemia (AA). 16 patients had received chemotherapy before OTC. The average age of 24 patients was 22.80 ± 6.81 years. The average anti-Mullerian hormone (AMH) was 1.97 ± 2.12 ng/mL, and the average follicle-stimulating hormone (FSH) was 7.01 ± 4.24 IU/L in examination before OTC. FSH was greater than 10.0 IU/L in 4 cases. The pre-OTC laboratory tests showed that the average white blood cell (WBC) count was (3.33 ± 1.35) × 109/L, the average hemoglobin was 91.42 ± 22.84 g/L, and the average platelet was (147.38 ± 114.46) × 109/L. After injection of recombinant human granulocyte colony-stimulating factor (rhG-CSF), blood transfusion, and iron supplementation in pre-OTC treatment, the average WBC count was (4.91 ± 3.07) × 109/L, the average hemoglobin was 98.67 ± 15.43 g/L, and the average platelet was (156.38 ± 103.22) × 109/L. Of the 24 patients, 22 underwent laparoscopic bilateral partial oophorectomy and oophoroplasty, and 2 underwent laparoscopic unilateral oophorectomy. The average duration of OTC was 59.54 ± 17.58 min, and the average blood loss was 32.1 ± 41.6 mL. The maximum blood loss was 200 mL. There was no significant difference in WBC count and hemoglobin concentration after OTC compared to pre-OTC period. Only the platelet count after OTC surgery was significantly different from that before surgery ([134.54 ± 80.84 vs. 156.38 ± 103.22] × 109/L, p < 0.05). None of the 24 patients had serious complications after OTC. 2 patients had mild infection symptoms, but both recovered well. 23 patients underwent hematopoietic stem cell transplantation (HSCT) after OTC. The median and interquartile range from OTC to the pretreatment of HSCT was 33 (57) days, and the median and interquartile range from OTC to HSCT was 41 (57) days. Seven of them began pretreatment of HSCT within 20 days and began HSCT within 30 days after OTC. All patients were followed up. Of the 23 patients who underwent HSCT after surgery, 22 presented with amenorrhea and 1 with scanty menstrual episodes. Seven patients underwent hormone replacement therapy (HRT) after HSCT. A patient with AA underwent ovarian tissue transplantation (OTT) 3 years after HSCT and resumed regular menstruation 6 months after OTT. CONCLUSIONS: Ovarian tissue cryopreservation has a promising future in fertility protection in patients with hematological diseases. However, patients with hematological malignancies often have received gonadotoxic therapy before OTC, which may be accompanied by myelosuppression while patients with non-malignant hematological diseases often present with severe hemocytopenia. So perioperative complete blood count of patients should be paid attention to. There was no significant difference in the WBC count and hemoglobin concentration in patients with hematological diseases before and after OTC surgery, and the platelet count decreased slightly within the normal range. Infection is the most common post-OTC complication, and HSCT pretreatment can be accepted as early as the 10th day after OTC. OTC has no adverse effects on patients with hematological diseases and does not delay HSCT treatment. For young patients with hematological diseases, OTC is an effective method of fertility preservation.

[Study on chemical components of Hypericum himalaicum and mechanism of anti-inflammatory based on network pharmacology and molecular docking technology].

The chemical constituents of ethyl acetate from Hypericum himalaicum were isolated by silica gel column chromatography, gel column chromatography, and high-performance liquid chromatography. The structure of the isolated compounds was identified by modern spectral techniques(NMR, MS, IR, and UV), and the potential anti-inflammatory targets and action pathways were analyzed and predicted by network pharmacology and molecular docking methods.Ten compounds were isolated from H. himalaicum and identified as 5,9,11-trihydroxy-3,3-dimethyl-3H,8H-benzo[6,7][1,4]dioxepino[2,3-f]chromen-8-one(1), betulinic acid(2), demethyltorosaflavone C(3), kaempferol(4), quercetin(5), hyperwightin B(6), toxyloxanthone B(7), 1,7-dihydroxy-xanthone(8), emodin(9), and 1,7-dihydroxy-4-methoxy-xanthone(10). Among them, compound 1 was a new compound, and compounds 2-10 were isolated from H. himalaicum for the first time. Network pharmacology screened 60 key anti-inflammatory targets. By acting on TNF, AKT1, CASP3, and other key targets, involving PI3K-AKT signaling pathway, IL-17 signaling pathway, VEGF signaling pathway, MAPK signaling pathway, and other signaling pathways, and phosphorylation, cell migration and movement, protein tyrosine kinase, and other biological processes were regulated to achieve anti-inflammatory effects. The results of molecular docking show that the above components have good binding properties with the core targets.

Network pharmacology and experimental evaluation strategies to decipher the underlying pharmacological mechanism of Traditional Chinese Medicine CFF-1 against prostate cancer.

Prostate cancer (PCa) is a common malignancy in elderly men. We have applied Traditional Chinese Medicine CFF-1 in clinical treatments for PCa for several years. Here, we aimed to identify the underlying mechanism of CFF-1 on PCa using network pharmacology and experimental validation. Active ingredients, potential targets of CFF-1 were acquired from the public databases. Subsequently, protein-protein interaction (PPI) and the herbs-active ingredients-target network was constructed. A prognostic model for PCa was also constructed based on key targets. In vitro experiments using PCa cell lines CWR22Rv1 and PC-3 were carried out to validate the potential mechanism of CFF-1 on PCa. A total of 112 bioactive compounds and 359 key targets were screened from public databases. PPI and herbs-active ingredients-target network analysis determined 12 genes as the main targets of CFF-1 on PCa. Molecular docking studies indicated that the primary active ingredients of CFF-1 possess strong binding affinity to the top five hub targets. DNMT3B, RXRB and HPRT1 were found to be involved in immune regulation of PCa. In vitro, CFF-1 was found to inhibit PCa cell proliferation, migration, invasion and induce apoptosis via PI3K-Akt, HIF-1, TNF, EGFR-TKI resistance and PD-1 checkpoint signaling pathways. This study comprehensively elucidates the underlying molecular mechanism of CFF-1 against PCa, offering a strong rationale for clinical application of CFF-1 in PCa treatment.

Dichroa febrifuga Lour.: A review of its botany, traditional use, phytochemistry, pharmacological activities, toxicology, and progress in reducing toxicity.

ETHNOPHARMACOLOGICAL RELEVANCE: Dichroa febrifuga Lour., a toxic but extensively used traditional Chinese medicine with a remarkable effect, is commonly called "Changshan" in China. It has been used to treat malaria and many other parasitic diseases. AIM OF THE REVIEW: The study aims to provide a current overview of the progress in the research on traditional use, phytochemistry, pharmacological activities, toxicology, and methods of toxicity reduction of D. febrifuga. Additionally, further research directions and development prospects for the plant were put forward. MATERIALS AND METHODS: The article uses "Dichroa febrifuga Lour." "D. febrifuga" as the keyword and all relevant information on D. febrifuga was collected from electronic searches (Elsevier, PubMed, ACS, CNKI, Google Scholar, and Baidu Scholar), doctoral and master's dissertations and classic books about Chinese herbs. RESULTS: 30 chemical compounds, including alkaloids, terpenoids, flavonoids and other kinds, were isolated and identified from D. febrifuga. Modern pharmacological studies have shown that these components have a variety of pharmacological activities, including anti-malarial activities, anti-inflammatory activities, anti-tumor activities, anti-parasitic activities and anti-oomycete activities. Meanwhile, alkaloids, as the material basis of its efficacy, are also the source of its toxicity. It can cause multiple organ damage, including liver, kidney and heart, and cause adverse reactions such as nausea and vomiting, abdominal pain and diarrhea. In the current study, the toxicity can be reduced by modifying the structure of the compound, processing and changing the dosage forms. CONCLUSIONS: There are few studies on the chemical constituents of D. febrifuga, so the components and their structure characterization contained in it can become the focus of future research. In view of the toxicity of D. febrifuga, there are many methods to reduce it, but the safety and rationality of these methods need further study.

Melatonin mitigates manganese-induced neural damage via modulation of gut microbiota-metabolism in mice.

Manganese (Mn), a common environmental and occupational risk factor for Parkinson's disease (PD), can cause central nervous system damage and gastrointestinal dysfunction. The melatonin has been shown to effectively improve neural damage and intestinal microbiota disturbances in animal models. This research investigated the mechanism by which exogenous melatonin prevented Mn-induced neurogenesis impairment and neural damage. Here, we established subchronic Mn-exposed mice model and melatonin supplement tests to evaluate the role of melatonin in alleviating Mn-induced neurogenesis impairment. Mn induced neurogenesis impairment and microglia overactivation, behavioral dysfunction, gut microbiota dysbiosis and serum metabolic disorder in mice. All these events were reversed with the melatonin supplement. The behavioral tests revealed that melatonin group showed approximately 30 % restoration of motor activity. According to quantitative real time polymerase chain reaction (qPCR) results, melatonin group showed remarkable restoration of the expression of dopamine neurons and neurogenesis markers, approximately 46.4 % (TH), 68.4 % (DCX in hippocampus) and 48 % (DCX in striatum), respectively. Interestingly, melatonin increased neurogenesis probably via the gut microbiota and metabolism modulation. The correlation analysis of differentially expressed genes associated with hippocampal neurogenesis indicated that Firmicutes-lipid metabolism might mediate the critical repair role of melatonin in neurogenesis in Mn-exposed mice. In conclusion, exogenous melatonin supplementation can promote neurogenesis, and restore neuron loss and neural function in Mn-exposed mice, and the multi-omics results provide new research ideas for future mechanistic studies.

The investigation on sialic acid-modified pectin nanoparticles loaded with oxymatrine for orally targeting and inhibiting the of ulcerative colitis.

The aim of the study was to develop an oral targeting drug delivery system (OTDDS) of oxymatrine (OMT) to effectively treat ulcerative colitis (UC). The OTDDS of OMT (OMT/SA-NPs) was constructed with OMT, pectin, Ca2+, chitosan (CS) and sialic acid (SA). The obtained particles were characterized in terms of particle size, zeta potential, morphology, drug loading, encapsulation efficiency, drug release and stability. The average size of OMT/SA-NPs was 255.0 nm with a zeta potential of -12.4 mV. The loading content and encapsulation efficiency of OMT/SA-NPs were 14.65% and 84.83%, respectively. The particle size of OMT/SA-NPs changed slightly in the gastrointestinal tract. The nanoparticles can delivery most of the drug to the colon region. In vitro cell experiments showed that the SA-NPs had excellent biocompatibility and anti-inflammation, and the uptake of SA-NPs by RAW 264.7 cells was time and concentration-dependent. The conjugated SA can help the internalization of NPs into target cells. In vivo experiments showed that OMT/SA-NPs had a superior anti-inflammation effect and the effect of reducing UC, which was attributed to the delivery most of OMT to the colonic lumen, the specific targeting and retention in colitis site and the combined anti-inflammation of OMT and NPs.

Inhibitory Efficacy of Main Components of Scutellaria baicalensis on the Interaction between Spike Protein of SARS-CoV-2 and Human Angiotensin-Converting Enzyme II.

Blocking the interaction between the SARS-CoV-2 spike protein and the human angiotensin-converting enzyme II (hACE2) protein serves as a therapeutic strategy for treating COVID-19. Traditional Chinese medicine (TCM) treatments containing bioactive products could alleviate the symptoms of severe COVID-19. However, the emergence of SARS-CoV-2 variants has complicated the process of developing broad-spectrum drugs. As such, the aim of this study was to explore the efficacy of TCM treatments against SARS-CoV-2 variants through targeting the interaction of the viral spike protein with the hACE2 receptor. Antiviral activity was systematically evaluated using a pseudovirus system. Scutellaria baicalensis (S. baicalensis) was found to be effective against SARS-CoV-2 infection, as it mediated the interaction between the viral spike protein and the hACE2 protein. Moreover, the active molecules of S. baicalensis were identified and analyzed. Baicalein and baicalin, a flavone and a flavone glycoside found in S. baicalensis, respectively, exhibited strong inhibitory activities targeting the viral spike protein and the hACE2 protein, respectively. Under optimized conditions, virus infection was inhibited by 98% via baicalein-treated pseudovirus and baicalin-treated hACE2. In summary, we identified the potential SARS-CoV-2 inhibitors from S. baicalensis that mediate the interaction between the Omicron spike protein and the hACE2 receptor. Future studies on the therapeutic application of baicalein and baicalin against SARS-CoV-2 variants are needed.

Drought priming at seedling stage improves photosynthetic performance and yield of potato exposed to a short-term drought stress.

Potato (Solanum tuberosum L.) is an important food and vegetable crop worldwide. In recent years, the arid environment resulting from climate change has caused a sharp decline in potato yield. To clarify the effect of drought priming at the seedling stage on the tolerance of potato plants to drought stress during tuber expansion, we conducted a pot experiment to investigate the physiological response of the plants generated from seed potatoes of the variety 'Favorita' to varied water supply conditions: normal water supply at the seedling stage (control), normal water supply at the seedling stage and drought stress at the mid-tuber-expansion stage (non-primed), and drought priming at the seedling stage plus drought stress at the mid-tuber-expansion stage (primed). Drought priming resulted in an increase in the number of small vascular bundles in potato plants compared to non-primed plants. It also altered the shape and density of stomata, enhancing water use efficiency and reducing whole-plant transpiration. The primed plants maintained the basal stem cambium for a longer time under drought stress, which gained an extended differentiation ability to generate a greater number of small vascular bundles compared to non-primed plants. Drought priming increased the amount and rate of dry matter translocation, and so reduced the adverse effects on tubers of potato under drought stress. Therefore, drought priming at the seedling stage improved the photosynthetic performance and yield, and probably enhanced the drought tolerance of potato.

Jiawei guomin decoction regulates the degranulation of mast cells in atopic dermatitis mice via the HIS/PAR-2 pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Guomin decoction (GMD) is a traditional Chinese medicine commonly used in clinical practice. It has traditionally been used to treat all allergic diseases. Currently, Jiawei Guomin Decoction (JWGMD) is used to treat sensitive skin after initial therapy. Although it has a significant clinical therapeutic effect, the exact role of mast cell degranulation in treating atopic dermatitis (AD) is still unclear. AIM OF THE STUDY: GMD and JWGMD can both treat allergic diseases, while JWGMD focuses on skin allergies. This study aims to explore the potential effect of JWGMD on the degranulation of mast cells in an AD mouse model induced by 2,4-dinitrofluorobenzene (DNFB) and investigate the effectiveness of JWGMD in alleviating disease progression to further provide specific therapeutic targets for treating AD. MATERIALS AND METHODS: The scratching times and skin lesions of model mice induced by DNFB were observed, and skin tissues were collected for subsequent measurement. Histopathological changes in the back skin of mice were observed by haematoxylin eosin (H&E) staining, Toluidine blue staining was used to detect the degranulation of mouse skin mast cells, and the relationship between the expression of histamine (HIS), mast cell tryptase (MCT) and mast cell degranulation was analysed by enzyme-linked immunosorbent assay (ELISA). The expression of protease-activated receptor-2 (PAR-2), histamine 1 receptor (H1R), H2R, H4R and MCT proteins in AD mice was detected by Western blot (WB). Immunofluorescence assay (IFA) further confirmed the localization of PAR-2, H1R, H2R, H4R, and MCT proteins in the skin. Quantitative real-time PCR (qPCR) was used to determine PAR-2, H1R, H2R and H4R mRNA levels in skin lesions to further clarify the mechanism by which JWGMD amplifies mast cell degranulation in AD. In addition, a reliable ultrahigh-performance liquid chromatography-quadrupole electrostatic field orbitrap mass spectrometry (UPLC-QE-MS) nontargeted metabolomics analysis was performed to analyse the differences in metabolite abundance between GMD and JWGMD, and these results were used to identify the active components in JWGMD that may have antipruritic and anti-inflammatory properties and inhibit mast cell degranulation. RESULTS: After intermittent stimulation with DNFB, the skin lesions showed extensive desquamation, dryness, scabbing, skin thickening, and slight bleeding. Both treatments alleviated this phenomenon and reduced the number of scratches, with JWGMD being the most effective. JWGMD can significantly reduce inflammatory cell infiltration, oedema, and some capillary neogenesis in mice and reduce the degranulation of mast cells. The ELISA results showed that JWGMD can increase the levels of MCT and HIS proteins. The WB and IFA results demonstrated that JWGMD reduced the expression levels of PAR-2, H1R, H4R, and MCT proteins in skin lesions, with protein localization mainly in the epidermal layer, while H2R protein levels were increased and mainly localized in the dermis. In addition, JWGMD downregulates the mRNA expression of PAR-2, H1R, H2R, and H4R. Interestingly, through UPLC-QE-MS nontargeted metabolomic analysis, we detected the anti-inflammatory and antiallergy active substances in JWGMD, such as methyl eugenol, dictamnine and sinapine. CONCLUSIONS: JWGMD may alleviate itching through methyl syringol, dictamnine, sinapine and other substances, and its mechanism may be related to inhibiting the HIS/PAR-2 pathway in AD model mice and further regulating the self-amplification of mast cell degranulation. JWGMD is a potential drug for treating AD. Therefore, it deserves continuous attention and research.

Total flavonoids of Litchi chinensis Sonn. seed inhibit prostate cancer growth in bone by regulating the bone microenvironment via inactivation of the HGFR/NF-κB signaling pathway.

ETHNOPHARMACOLOGICAL RELEVANCE: Litchi chinensis Sonn. (Litchi) seed, a traditional Chinese medicine, is habitually used in the clinical treatment of prostate cancer (PCa)-induced bone pain. In our previous study, flavonoids have been identified as the active ingredient of litchi seed against PCa. However, its anti-tumor activities in bone and associated molecular mechanisms are still unclear. AIM OF THE STUDY: To investigate the effects and underlying mechanisms of total flavonoids of litchi seed (TFLS) on the growth of PCa in bone. MATERIALS AND METHODS: The effect of TFLS on the growth of PCa in bone was observed using a mouse model constructed with tibial injection of luciferase-expressing RM1-luc cells. Conditioned medium (CM) from bone marrow stromal cells OP9 and CM treated with TFLS (T-CM) was used to investigate the effect on the proliferation, colony formation, and apoptosis of PCa cells (LNCaP, PC3, RM1). An antibody microarray was performed to detect cytokine expression in the supernatant fraction of OP9 cell cultures treated with TFLS or left untreated. Western blot assay was employed to determine the expression and activity of HGFR and its key downstream proteins, Akt, mTOR, NF-κB, and Erk, in PCa cells. The potential target was further verified using immunofluorescence and immunohistochemistry assays. RESULTS: Treatment with TFLS (80 mg/kg, 24 days) significantly suppressed the growth of RM1 cells in bone. CM from bone marrow stromal cells OP9 stimulated the proliferation and colony formation of the PCa cells as well as inhibited the apoptosis of PC3 cells, while T-CM reversed the effects mediated by OP9 cells in vitro. In an antibody array assay, TFLS regulated the majority of cytokines in OP9 cell culture supernatant, among which HGF, HGFR, IGF-1R, and PDGF-AA showed the greatest fold changes. Mechanistically, CM upregulated HGFR and promoted phosphorylation of NF-κB while T-CM induced reduction of HGFR and dephosphorylation of NF-κB in PC3 cells. Moreover, T-CM inhibited NF-κB entry into PC3 cell nuclei. Data from in vivo experiments further confirmed the inhibitory effects of TFLS on NF-κB. CONCLUSION: TFLS suppresses the growth of PCa in bone through regulating bone microenvironment and the underlying mechanism potentially involves attenuation of the HGFR/NF-κB signaling axis.

Network meta-analysis of different liver protective drugs in the treatment of drug-induced liver injury.

BACKGROUND: Currently, drug-induced liver injury (DILI) has become one of those public issues in society, which has added a huge burden to both the individuals and the society. In the current clinical stage, there are numerous drugs developed to treat this disease, and different drug treatment measures have been proven to achieve certain clinical efficacy in the corresponding randomized controlled trials. However, there are still many therapeutic drugs that have not been directly compared and studied. Therefore, it is difficult to directly compare the effectiveness and safety of various strategies for the treatment of DILI. In this regard, the present study collected the therapeutic efficacy of diverse treatments in DILI in recent years through network meta-analysis, evaluated and screened the existing optimal clinical therapeutic plan, and helped physicians formulate clinical therapeutic plans. METHODS: Databases, including the Chinese Journal Full-text Database, Wanfang Data Journal Paper Resources (Wangfang), VIP Chinese Science and Technology Journal Full-text Database, The Cochrane Library, PubMed, and EMBASE, were searched using keywords from inception to January 2023. Eligible randomized controlled trials were selected in line with eligibility criteria, and mesh meta-analysis of binary variables was carried out using Stata 16 software. CONCLUSION: In combination with alanine aminotransferase, aspartate aminotransferase, and total bilirubin, MI may be the intervention measure for minimizing alanine aminotransferase levels in patients after treatment. Besides, compound glycyrrhizin may be the intervention for minimizing aspartate aminotransferase levels in patients after treatment, and polyene phosphatidylcholine may be the intervention for minimizing total bilirubin levels in patients after treatment. Placebo is the potential intervention that has the least adverse reactions post-treatment, and RT has the second least adverse reactions. Moreover, hepatocyte growth-promoting factors may be the most effective intervention after treatment. RESULTS: To sum up, the present work compared the clinical effects of 13 liver protective drugs through meta-analysis and provided a systematic understanding of commonly used drugs for the treatment of DILI in clinical practice.

[Research progress on structure, structure-activity relationship, and biological activity of Aconiti Lateralis Radix Praeparata polysaccharides].

Aconiti Lateralis Radix Praeparata polysaccharides(AP) are a class of bioactive macromolecules extracted from the herbs of Aconiti Lateralis Radix Praeparata and its various processed products. Since the AP was first separated in 1986, its pharmacological effects include immune regulation, anti-tumor, anti-depression, organ protection, hypoglycemia, and anti-inflammatory had been found. In recent years, with the development of polysaccharide extraction, separation, and structure identification technologies, more than 20 kinds of AP have been separated from Aconiti Lateralis Radix Praeparata and its processed products, and they have ob-vious differences in relative molecular weight, monosaccharide composition, glycosidic bond, structural characteristics, and biological activities. In particular, AP may be dissolved, degraded, or allosteric under the complex processing environment of fermentation, soaking, cooking, etc., leading to the diversified structure of AP, which provides a possibility for further understanding of the structure-activity relationship of AP. Therefore, this study systematically reviewed the research progress on the structure and structure-activity relationship of AP, summarized the biological activity and potential action mechanism of AP, and discussed the technical challenges in the development and application of AP, so as to promote the quality control and further development and utilization of AP.

Network Pharmacology and Molecular Docking Explore the Mechanism of Mubiezi-Yinyanghuo Herb Pair in the Treatment of Rheumatoid Arthritis.

Objective: Our previous studies have shown that the Mubiezi-Yinyanghuo (MBZ-YYH) herb pair inhibits rheumatoid arthritis (RA) cell proliferation and glycolysis, promising results with an obscure mechanism of action. Methods: Therefore, it is necessary to explore the main components of MBZ-YYH and unravel the potential mechanism in RA based on network pharmacology and molecular docking methods. Components and targets of MBZ-YYH were retrieved from the TCMSP. Relevant targets of RA were searched in GeneCards, therapeutic target database (TTD), and DisGeNET databases; the common targets of the MBZ-YYH compounds and RA were obtained by comparison; and a component-target interaction network was established by Cytoscape 3.9.1. Gene ontology (GO) analysis and Kyoto Encyclopedia of Gene and Genome (KEGG) pathway enrichment analysis were performed through the David database. Molecular docking was performed by PyMoL2.3.0 and AutoDock Vina1.1.2 software. Results: 7 active ingredients and 58 putatively identified target genes were screened from MBZ, and 16 effective components of YYH and 230 potential targets were identified. There were 29 mutual targets between the two herbs and RA. Through the PPI network, 9 hub targets which contain JUN, CASP3, PPARG, PTGS2, GSK3B, CASP8, HMOX1, ICAM1, and HK2 were screened out. GO term enrichment analysis indicated that positive regulation of the apoptotic process, response to drugs, and response to hypoxia were significantly enriched. Based on KEGG analysis, it was mainly associated with the IL-17 signaling pathway, the TNF signaling pathway, and the p53 signaling pathway. The docking analysis revealed that the effective components showed strong binding activity with the receptors. Conclusion: The effects of the MBZ-YYH herb pair on RA were coordinated by the interaction of diverse components, which may be through the IL-17 signaling pathway and the TNF signaling pathway, which target GSK3B, HK2, caspase 3, and caspase 8, inhibiting the proliferation and glycolysis of rheumatoid arthritis fibroblast-like synovial cells (RA-FLS) and tending towards an increasing efficacy and decreasing toxicity effect on RA.

Effects of extracted oil of fermented Tartary buckwheat on lipid-lowering, inflammation modulation, and gut microbial regulation in mice.

This study investigated the composition of Tartary buckwheat oil fermented by Monascus purpureus and extracted under supercritical CO2 conditions (FTBO) and evaluated its effects on lipid-lowering, inflammation modulation, and gut microbial regulation in mice that were fed a high-fat diet (MOD). Compared with the raw oil (TBO), the γ-oryzanol content reached 27.09 mg g-1; the monounsaturated fatty acid (MUFA) content (such as oleic acid and palmitic acid) was elevated; and the antioxidant capacities of DPPH, ABTS, and hydroxyl were improved in FTBO (p < 0.0001). Then, supplementation with FTBO had a remarkable effect on reducing the body weight and visceral obesity as well as alleviating hyperglycemia, dyslipidemia, inflammatory reactions, and liver damage. The TC, TG, and LDL-C levels in the liver and plasma were reduced, and the HDL-C levels in the liver were increased (p < 0.05). In particular, the high-dose group (FTBOH) exhibited the most significant effect on reducing the pro-inflammatory cytokines ET, TNF-α, IL-1ß, and IL-6 in the liver, which were 18.85, 570.12, 50.47, and 26.22 pg mL-1, respectively (p < 0.05). Moreover, FTBO reversed intestinal disorders and increased the intestinal microbial diversity and richness. The relative abundance of beneficial bacteria, such as Bifidobacterium, Lactobacillus, Limosilactobacillus, and Lachnospiraceae_UCG-006, were increased, and the relative abundance of the harmful bacteria Staphylococcus and Lachnoclostridium were reduced. In summary, FTBO has potential applications as a dietary supplement or dietary modifier in lowering blood lipids, modulating immune activity, and reversing intestinal disorders. This study provides reference guidance for the subsequent industrialization and development of Tartary buckwheat, the extension of the industrial chain, the development of new products, and the extraction of functional components.

Iron and Steel Industry Emissions: A Global Analysis of Trends and Drivers.

The iron and steel industry (ISI) is important for socio-economic progress but emits greenhouse gases and air pollutants detrimental to climate and human health. Understanding its historical emission trends and drivers is crucial for future warming and pollution interventions. Here, we offer an exhaustive analysis of global ISI emissions over the past 60 years, forecasting up to 2050. We evaluate emissions of carbon dioxide and conventional and unconventional air pollutants, including heavy metals and polychlorinated dibenzodioxins and dibenzofurans. Based on this newly established inventory, we dissect the determinants of past emission trends and future trajectories. Results show varied trends for different pollutants. Specifically, PM2.5 emissions decreased consistently during the period 1970 to 2000, attributed to adoption of advanced production technologies. Conversely, NOx and SO2 began declining recently due to stringent controls in major contributors such as China, a trend expected to persist. Currently, end-of-pipe abatement technologies are key to PM2.5 reduction, whereas process modifications are central to CO2 mitigation. Projections suggest that by 2050, developing nations (excluding China) will contribute 52-54% of global ISI PM2.5 emissions, a rise from 29% in 2019. Long-term emission curtailment will necessitate the innovation and widespread adoption of new production and abatement technologies in emerging economies worldwide.

Metabolic regularity of bioactive compounds in Bufei Jianpi granule in rats using ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry analysis technology.

Bufei Jianpi granule (BJG) is clinically effective for treating chronic obstructive pulmonary disease (COPD). At present, there is no report regarding the drug metabolism of BJG in vivo. This work developed an ultra-high-performance liquid chromatography coupled with triple quadrupole mass spectrometry method with high accuracy and sensitivity to determine drug metabolism of this compound in vivo. After continuous administration of BJG, the concentrations of 10 components in rat plasma, namely betaine, peimine, peiminine, astragaloside A, sinensetin, nobiletin, naringin, calycosin, formononetin, and magnolol, were determined at different time points. Meanwhile, the pharmacokinetic parameters and metabolic rules of these 10 components were evaluated: Cmax , 8.624-574.645 ng/mL; Tmax , 0.250-8.667 h; AUC0-t , 17.640-8947.393 ng h/mL; T1/2 , 3.405-66.014 h; mean residence time (MRT), 6.893-11.223 h. All these components possessed anti-inflammatory, antioxidant, and other biological activities to varying degrees, contributing to improving lung function, mitigating pneumonia and pulmonary fibrosis, and preventing and treating chronic obstructive pulmonary disease. Exploring the pharmacokinetic parameters and the laws of chemical components in BJG forms the scientific basis for applying the compound clinically and identifying quality markers for the control of the compound.
